  • Skills work Noticing causes and effects Some texts are about how factors affect each other. They may examine the reasons why something happended (the causes), or they may examine what happens because of something else (the effects). Being able to identify the difference between causes and effects is an important reading skill. Look at the examples of causes and effects: Cause Effect We use too much water, so we are running out of it. Higher temperature lead to more evaporation. Effect Cause We are running out of water because we use to much of it. More evaporation is a result of higher temperatures. 5 min.
  • a. Underline the causes. 1. Aquifers are being overused,which causes them to go dry. 2. Mismanagement of the environment can lead to changes to our water resources. 3. Clouds are a result of moisture cooling in the atmosphere. 4. There will be more evaporation because of higher temperatures. 5. Irrigation projects remove water from rivers, which can cause rivers to run dry. 6. Ice melts into the sea because of global warming. 5 min.
  • b. Underline the effects. 1. Paul was careful with his expenses so he saved money. 2. Using less water will be a result of changing attitudes and habits. 3. The buses didn’t run because of the heavy rain. 4. Bad eating habits can lead to poor nutrition. 5. Many people are buying electric cars so they can be envirinmentally friendly. 6.

Effective water usage results from good government policies. 8. Ice can float on water as the result of it being 9 percent lighter than water from the air it contains. 5 min. Causes → Effects Effects → Causes Overusing water leads to water shortages. causes results in brings about Water shortages result from overusing water. are caused by are the result of are brought about by
  • Writing Complete the paragraph with the correct cause and effect phrases. Cause and effect in Science Scientists try to find cause and effect relationships. For example, the moon pulls on the earth and (1) causes the sea level to change, which (2) leads to flooding, especially if there is a storm. In a similar way, scientists can study the damage to our oceans which results (3) from pollution (4) caused by humans. For example, they can measure how much dumping waste into the oceans results (5) in of change to the natural environment. Scientists can also see how poor nutrition is a result (6) of poor eating habits and see how a better diet (7) brings about better health. 5 min.
  • When you look in a dictionary, look for word families. These are groups of words that share the same basic meaning but have different affixes. For example, use, user, used, useful, uselessness are all part of the word family use. Check which words are nouns (n), verbs (v), and adjectives (adj). Science (n) The study of natural things and how they behave. Many discoveries in science are accidents. Scientific (adj) Scientific research is a source of much human knowledge. Discover (v) If you discover something you did not know before, you learn about it. He discovered an old temple. Discovers, discovering, discovered. Discovery (n) I made a great discovery this morning.Use a dictionary to find word family members Skill Builder

  • b) Read the text and look at the diagram. Then write the letters in the correct places. When processing seawater with a distillation process, first the water is cleaned. Then it is heated in a vacuum to 85º (as it is in a vacuum it reaches boiling point at a lower temperature, thus saving energy) to create steam. As the steam is treated before putting it into the water supply system. 6 min. 1. I 2. E 3. J 4. G 5. C 6. F 7. A 8. H 9.
